Abstract

A rupturable fluid flow indicator and a rupture disk assembly including the indicator are provided. The indicator is comprised of a rupturable member adapted to be clamped across a fluid flow passageway having at least one opening formed therein for weakening a portion of the member. An electric current conductor adapted to be electrically connected in an alarm circuit is attached across the weakened portion of the rupturable member whereby when the member ruptures as a result of fluid pressure exerted thereon, the conductor also ruptures.
